SKATE-CLAMP.

Specification of Letters Patent.

Patented Mar. 13, 1917.

Application filed August 16, 1915. Serial No. 45,807.

To all whom it may concern:

Be it known that I, HARRY E. KALAN UIN, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Skate-Clamps, of which the following is a specification.

This invention relates to an improvement in skate clamps, and has for its primary object to provide a clamp or vise which will secu rely hold both the skates and the file while the former are being sharpened.

Another object is to provide an apparatus of the above description which is simple and cheap, and which is strong and easily adjustable to different skates. Another object .is to provide a simple device by the use of which skates may be easily hollow-ground.

My invention consists of the new parts and combinations of parts which will be hereinafter described in the specification, defined by the claims, and shown in the ac companying drawings.

in the accompanying drawings I have slnnvn my invention in the form which is now preferred by me.

*igure 1 is a perspective view showing my invention in use.

Fig. 2 is a longitudinal central section of the skate clamp.

Fig. 3 is a section on the line 33 of Fig. 2.

Fig. lis a detail fragmentary perspective view showing the manner of connecting the adjustable clamping bars.

Fig. 5 is a perspective view of the trackway bars detached.

Fig. 6 is a perspective view of the sliding carriage.

Fig. 7 is a perspective view of the file clamp detached from the sliding carriage.

Referring in detail to the drawings 5 and 6 designate the inner and outer members of two pairs of clamping bars. These bars are of angular form in cross-section, the bars 5 and 6 having their horizontal flanges disposed in the same plane, at the opposite ends of the clamp. The outer bar, 6, of one pair is connected to the inner bar, 5, of the other pair of clampingbars by a metal plate, 7, which is disposed upon the horizontal flanges of the bars and bolted or riveted thereto, as at 8.

The metal plate, 7 at one end, extends beyond the inner edge of the clamping bar,

5, and laps over upon the horizontalflange of the opposed clamping bar, 6.

The vertical flanges of the clamping bars, 5, and 6, are provided at their opposite ends with alined openings, 9, to receive the clamping screws, 10. Upon the inner ends of thesesorcws, nuts, 11, are threaded, said nuts being of polygonal form and abutting closely against the under side of the connecting plates, 7, so that said nuts are positively held against turning movements upon the screws. The outer ends of the screws, 10, are provided with suitable finger pieces whereby said screws may be readily rotated.

In using my improved clamp, it is unnecessary to remove the skates from the shoes to which they are attached, but the operator simply loosens the clamping bars by turning the screws, 10, so-that by pulling the outer clamping bars, 6, in opposite directions, the inner edges of the horizontal flanges of said bars will be spaced from the opposed edges of the clamping bars, 5, the verical flanges of the clamping bars shifting freely upon the screws, 10. The skate blades, indicated at B, are then inserted upwardly through the spaces or slots produced between the clamping bars. The operator now turns the screws, 10, in the proper di rection to thread the same through the nuts, 11, thus drawing the vrespective pairs of clamping bars tightly against the skate blades. There is thus a clamping action of the inner edges of the horizontal flanges of the bars, 5 and 6, against the sides of the skate blade throughout the length thereof. In this manner, it will be seen that the skate blades are absolutely held against movement. The parts shown in Figs. 5, 6 and 7, when combined, permit the blades to be hollow ground without removing either skate. The second blade is ground by removing the carriage and reversing it, and adjusting it, if necessary, as for the first skate.

To provide a simple means for grinding the skates after they have been clamped in place, I employ the devices shown detached in Figs. 5, 6 and 7. A pair of trackway bars 14 are adjustably secured between the clamp members and parallel thereto to two of the plates 7, by means of set screws 13. End spacers 25 hold the bars 14 separated, and are secured thereto by any suitable means, as by screws 2%.

A plate 1 7 has grooves 26 upon its under side, which receive trackway bars 14;, and is adapted to slide lengthwise the clamp. A vertical plate 15, secured thereon, carries a clamp 22 vertically adjustable thereon by means of set screw 16. T his clamp consists of a bar 22 with its ends bent twice inward substantially at right angles. Upon the ends are secured spring clamps, in the form of U-shaped clips 19, provided with set screws 18. In these clamping members may be secured a file 20. I have shown this file as round, in order to hollow grind the skates.

When the skates are clamped in place, the file clamp is adjusted to bear upon the blade ll of the skate. The file clamp, with its carriage l7, now pushed back and forth. The tracl-zway bars, being parallel to the clamp, hold the file upon the skate, so that the blade may be hollow ground. \Vhen one skate has been ground, the carriage may be reversed, again adjusted, if necessary, and the second skate ground. T he device may he used for sharpening the blades of all types of skates now on the market. The skate blade may be easily, quickly, and securely clamped in place, without removing the shoes, and may be easily removed after being sharpened.

From the foregoing description taken in connection with the accompanying drawing, it will be seen that I have produced a device which is extremely strong and durable, highly convenient and serviceable in practical use, and may be produced at small manufacturing cost.

It is, of course, apparent that the angle bars may be made in various lengths and the several structural features of the device also considerably modified in form and propor tion without departing from the essential features or sacrificing any of the advantages of the invention as claimed.

Having thus fully described my invention, what I desire to claim and secure by Letters Patent is:

1. In a skate clamp, in combination, a pair of clamping members, a trackway alongside of and parallel to said clamping members, a carriage slidable thereon, and

means for clamping a file upon said carriage against movement relative thereto.

2. In a skate clamp, in combination, a pair of blade-clan'iping members, a trackway alongside of and parallel to said clamping members, a carriage slidable thereon, said carriage having a v rtical slot therein, a file clamp, and a screw passing through said vertical slot and securedin the file clamp to adjustahly secure the latter upon the carriage.

3. In a skate clamp, in combination, a pair of blade-clamping members, a trackway alongsiue of and substantially parallel to said clamping members, transverse slots in said clamping ,members, set-screws passing through said slots and secured in said trackway to adjust the position of the latter relative to the clamping members, a carriage slidable upon said trackway, and a file clamp secured thereon.

l. In a skate clamp, in combination, bladeclamping members, trackway bars extending alongside of and parallel to the bladeclamping members, means for adjusting said bars toward and from the blade-clamping members, a carriage provided with grooves upon its under t'ace adapted to receive said bars, and slidable thereon, and provided with a vertical plate, a plate vertically adjustable thereon, the ends of said plate being turned inward and spring file clamps secured upon the ends of said plate.

5. In a skate clamp, in combination, a pair of blade-clamping members, trackway bars alongside of and parallel to the clamping members, means for adjusting said bars toward in d from the clamping members, a carriage provided with grooves upon its under face adapted to receive said bars and slidable thereon, an upright plate provided with a vertical slot mounted upon said carriage, a second plate adjustably secured thereto by a set screw passing through said slot, the ends of said second plate being turned inward, and file clamps secured upon said ends, and adapted to secure a file against movement relative to the carriage.
